A Design Approach for Dual-Band Wilkinson Power Divider with Two Pairs of Coupled-Line Sections

Progress In Electromagnetics Research Letters, Vol. 45, 81-87, 2014
Abstract
This paper presents a design approach for dual-band Wilkinson power dividers. Two pairs of parallel coupled-lines are used to replace the quarter-wavelength transformers in the conventional Wilkinson power divider to obtain dual-band operation. Using even- and odd-mode analysis, the closed-form design equations are derived for design parameters and design procedures of the proposed dual-band power divider are given. For verification purpose, a practical power divider, which operates at 1 GHz and 2.1 GHz with 3 dB power dividing ratio, is designed, fabricated and tested. The simulated and measured results are in good agreement.
